Well i have an norn guardian and i know wut you mean but it prolly depends on your build, while my guardian mainly focuses on heal its pretty good help cause its power only depends on your lv, but if you are more damaging focused than a norn elite skill would do it too
so up to you and it maby would fit in your playingstyle if u like use spirit weapons :D
p.s. they should make it useable underwater : l
